Abstract: Enteral nutrition is the preferred nutritional therapy for critically ill patients, and early enteral nutrition intervention is particularly important during the recovery phase of critical illness. However, due to the complexity of their condition, critically ill patients often experience early enteral nutrition intolerance. Based on this, relevant literatures were reviewed to summarize the contributing factors, assessment methods, and preventive measures of early enteral nutrition intolerance. The aim is to provide a theoretical basis for clinical nursing practice to improve the nutritional status of critically ill patients, promote early recovery of gastrointestinal function, reduce mortality, and shorten hospital stays.

Key words: critically ill patients, early enteral nutrition, tolerance
